portion o seid iu'oe 2Q :and lie disohez'ge "the combination with -tubular sleeve said rotatable conveyer and means for lock-` From the above description, it will be apparent that power from 'a suitable source,

may be transmitted to the conveyer shaft 5, from the neck 32, by meansof the spider' 6 attached to the tubular sleeve 29, having the flange 30 keyed to said neck 32. It will also be seen that just prior to the complete discharge of a desired quantity of material, the clutch sleeve-21 is moved to the unclutched position, stopping the movement of the valvev 17, and discontinuing the feedA to the conveyer cylinder 2. In this case however, theconveyer is still rotated until the material is entirely discharged from the cylinder 2.

Having -fully described my invention, I claim:

l. In a device of the character described, a rotatable mill-casing provided with a reduced extension, of a stationary conveyer cylinder extending within said reduced extension, a rotatable conveyer extending longitudinally within said conveyer cylinder, a tubular sleeve arranged within said reduced extension, said tubular sleeve encircling a portion of said conveyer cylinder' and extending therebeyond within said reducedextension, means for locking said sleeve to said reduced extension and said rotatable conveyer, substantially as described. f

`2. In a device of the character described, the combination with a rotatable mill-casing provided with a reduced extension, of a stationary conveyer cylinder extending within said reduced extension, a rotatable conveyer extending longitudinally within said conveyer cylinder, means for connecting said rotatable conveyer, with said reduced extension, said means comprising a tubular sleeve provided with a flange, said tubular s'leeve being arranged between said conveyer cylinder and said reduced extension, said being rigidly connected to ing said flan e of said sleeve to said reduced extension, su stantially as described.

3. In a device' of the charactery described, the combination with a rotatable mill-casing provided with a reduced extension, of a stationary conveyer cylinder extending within said reduced extension, a rotatable conveyer extending longitudinally within'said conveyer cylinder, means for connecting said rotatable conveyer with said reduced extensaid spring extionary conveyer cylinder Ahopper provided with a sion, said means comprising a tubular sleeve provided with a. flanged portion, sald tu- `\bular sleeve being rigidly connected toisaid conveyer, meansl for locking the fianged portion of said sleeve to said reduced extension, an outer sleeve surrounding a portion of said conveyer cylinder and said reduced extension, and means forlocking said outer sleeve to said reduced extension, substantially as-described.

4. In a deviceof the character described, y the combination with a rotatable mill-casing provided with a reduced extension, of awstationary conveyer cylinder extending within said reduced extension, a tubular sleeve having a flanged portion arranged between said reducedl extension and said conveyer cylinder, means for locking the flanged portion 'of said tubular sleeve to said reduced extension, a rotatable conveyer sha-ft narranged longitudinally within said conveyer cylinder, said conveyer shaft being rigidly connected with. said sleeve and extending forwardly beyond said conveyer cylinder, a hopper provided w-ith a rotatable feed valve arranged upon the forward portion of said conveyer cylinder, means for rotating saids;y

feed valve, said means comprising a rotary member mounted upon said conveyershaft, a ratchet mechanism associated withl said feed valve, and an adjustable arm connecting said rotary member and saidratchet mechanism, substantially as described.

.5. In a device of the character described, the combination with .a rotatable mill casing provided with a reduced extension, of a staextending within said reduced extension, a tubular sleeve having a flanged lportion arranged between said reduced extension and said conveyer cylinder, means for locking the flanged portion of said tubular sleeve to said reduced extension, a rotatable conveyer shaft arranged longitudinally within said conveyer cylinder, said conveyer shaft being rigidly connected with said sleeve and extendin forwardly beyond said conveyer cylin er, a

arranged upon the forward portion of said conveyer cylinder, means for rotating said feed valve, member revolubly mounted upon said con.- veyer shaft, a clutch mechanism for locking sald rotary member to said shaft, a ratchet mechanism Vassociated with said feed valve, and .an 'adjustable arm connecting said rotary member and said ratchet mechanism, substantially as described.
